To all w/mm it may ("O/M6771.

Be it known that I, JOHN li jxowsui. a citizen of the United States, residing at Chicago, in the county of Cool: and State of Illinois, have invented certain new and 1 useful Improvements in Automobile Emergency-Wrenches; and I do hereby declare the following to be a full. clear, and exact 5 description of the invention, such as will enable others skilled in the art to which it appertains to ma kc and use the same.

This intention relates to new and use ful improvements in wrenches, and as its principal object contemplates the provision of a device of this character which is peculiarly adapted for employment with autom iles.

further object is to provide a wrench l which consists essentially in a number of hinwrenches of various sizes formed with i jawsof customary shape and designed in 1 such manner that nuts and bolts of any size within a reasonable range may he cfl'ccl lively and conveniently manipulated by merely pulling out the desired bar Wrench from the body casing which contains all of the bar wrenches. I

The above and additional objects are ac complishcd by ouch means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appentled hereto and form a part of this application.

\Vith reference to the drawings, wherein l have illustrated the preferred embodiment of my invention as it is reduced to practice, and throiwhout the several views of which similar re erence numerals designate correspontling parts: Figure 1 is a top plan View illustrating the various wrench bars in inoperative relation to each other and to the llOtlY casin Fig. 2 is a side elevation. Fig. 3 is a section on the line 3& of Fig. 2, Fig. 4 is an end view illustrating onel set of wrench jaws? Fig 5 i the line 5- T) of Fig. 2. Fig. 6 a detail View of the side plates employed in conneclion with the slidahle shanks of the bar l l l is :1 section on wrenches.

. Proceeding now to the description of the drawings, the numerals Il and 11 designate as an entirety the two sets of her Wrenches i which are arranged with their shanks s ably mounted e oo-Cl gti iiori Wliiii i: the hsndle the wrench (A I in Fig.

l 1a.. 1111 entirety b the numeral 12. Each bar wrench is of the ordinary and usual type, as will be obser ed particularly by reference to Fig. 3 with the exception that the free terminal of each bar wrench shank is enlarged at 13 to produce shoul- 101's l4 and 15, which by engagement with similar shoulders 16 out. 17 formed in the body portion 12. limit the outward moveshank. In this connection it is to he observed that the body portion is bifurcated from each terminal towar'l a central partition or stop wall. 18 whi h l concuvetl to conform to the rounded terminals of the shanks of the her Wrenches. As; will he readily discerned by reference to the wrench shanks are all formed with a loiigitudinally extending slot in each of which is mounted a leaf spring as at 151, this leaf spring is arranged to frictionand to slide over spacing plates 2f which are formed of thin sheet steel or any desired metallic substance, and are intel-posed hetwecri the various wrench shanks. The confornmtitm of these usem'hers 20 is I similar to that of the wrench shanks in that they are provided with stop shoulders which by engagement with the shoulders 16 and 17 operate to limit their outward movement when the various Wrench bars are with drawn from the body casing when put into operation.

The. bar wrench construction anti design of the various springs anti shoulders of the sets 10 and 11 are similar to the wrench jaws indicated at- 21 and mode of various sizes, as particularly illustrated in Fig.4. The pur ose of the variation in size of the wrench jaws will be apparent, for it is u foot of common knowledge that when main inc lmsly repairs, it 'iouru'l necessary to remove and apply nuts and bolts of various The shanks of the various 'o'ar wrenches arev held in assembled relation in the body portion by a. casing heretofore designated by the numeral 12. This casing is composed, respectively, 0: two sec-- tions, litll section being substantially U- shapr-(l in cross section and made of sheet brass. galvanized iron, or any other suitable I economical and practical motel-lat The two sections of the casing 12, to behereinafter (lFlfjl'illiBl'l by the numerals 21 and 21"., are

otual construction and arrangement of the various per-ts of wrench of this invention being thus disuosed. it now remains to describe the manner in which the various bar Wrenches are manipulated when it is desired llu arrange them inoperativeposiiion. Briefly ihe operation is as follower file Wrench which the operal or desires to e1; ''iii'idrtm'n from the body e. Wye. :h or bone. e to hri in 'o sadly-e positii' iruliosied in d Li lines in Fig. By roierenee to this figilYQflit will be noted that the wrenoh'jaw is projeeled beyond she Wrench jaws of ihe set and is in such position that it may be readily applied to any belt or nut in. the usual manner and that the body portion of the Wrench forms. a convenienthanslle foe manipulating the wreneh jaw. It is also to be observed that when the wrench jaws are in their operative and inoperaiive positions, the springs 19 by frictional engagement with the plate 20 to hold the shanks of the wrench in the desired arfljuialed position.

in reduction to practice, I ha e found y it the form oi my invention, illustrated in the drawings and referred to in thenbove description, as the preferred embodiment, is the most eiiieient and practical; realizx that conditions concurrent with the wiopeion of my device will. necessarily vary I desire to emphasize the fact that, Various minor el nges in delails of construction, propori ion and aerangement of arts may he resorted lo, when required Wit ioul; sacrificing any of the advantages of my invention, as defined in the appended claims.

Having thus described my im'ention, What I claim is:
